SEEGIIFIQATION forming part of Letters Patent No. 691 ,034, dated January 14, 1902. Application filed May 6. 1901. Serial No. 69.017. (No model.)

To ctZZ whom it may concern:

Be it known that we, EDWIN C. WILHARMS and ADOLPH J. WILHARMS, citizens of the United States, residing at Greenleaf, in the county of Brown and State of Wisconsin, have invented a new and'useful Pneumatic Feed- Oonveyer for Feed-Cutters, of which the following is a specification.

Our invention is an improved pneumatic feed-conveyer for feed-cutters; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

Our present invention is an improvement on the pneumatic conveyer for which Letters Patent of the United States No. 659,722 were granted to us October 16, 1900.

In the accompanying drawings, Figure 1 is a side elevation of a pneumatic feed-conveyer embodying our improvements, showing the same disposed in operative position on the fan-casing of the feed-cutting machine. Fig. 2 is a horizontal sectional view of the same, taken on a planeindicated by the line a a of Fig. 1. Fig. 3 is a vertical longitudinal sectional View of our improved pneumatic feedconveyer. Fig. 4 is a detail transverse sectional view of the same, taken on a plane indicated by the line Z) 6 of Fig. 1. Fig. 5 is a detail view, beingasection taken on a plane indicated by the line 0 c of Fig. 1.

The feed-cutting machine may be of any suitable construction and is provided with a blower or fan in a casing 1, as described in our before-mentioned Letters Patent, cut feed being discharged from the feed-cutter into the said casing l and blown upwardly from the same by the fan or blower through an opening in the upper side of said casing.

The pneumatic feed-conveyer is a tube composed of the lower section 2, the outer section 3, and the flexible elbow 4, which connects the same together. The lower section 2 has its lower side secured in a cylindrical sleeve 5, at the lower edge of which is a baseri-ng 6. Aspur-ring 7 revolves on the sleeve 5, bears on the base ring 6, and is provided with peripheral spurs 8. The upper side of the sleeve 5 projects above the spur-ring 7, and to the said projecting upper portion of the sleeve is rigidly secured a turning ring 9.

Thereby the spur-ring is swiveled on the lower section of the pneumatic feed-conveying tube and the latter is adapted to turn in said spur-ring. The said sleeve 5 protects the lower section 2 of the conveyer-tnbe from the wear which is occasioned by the friction of the spur-ring thereon in the form of our invention shown in our former patent. Furthermore, said sleeve materially strengthens the conveyer-tube at the point where it is subjected to the greatest stress. Said spurringis secured on the upper side of the casing 1 of the fan or blower by depending straps 10 or other suitable means, and hence the lower end or section of the feed-conveying tube is positioned on the said casing. The turning ring 9 is provided on one side with a. pair of standards 11 and is provided on the opposite side with a projecting arm 12. The said turning ring is further provided at a point between the standards 11 with a projecting lug 13, to which is pivoted a supporting-arm 14. The latter carries at its outer end a trolley-sheave 15, as described in our before-mentioned Letters Patent, which trolley-sheave operates in a guidewayon the under side of the outer section 3 of the pneumatic feed-conveying tube,said guideway being indicated at 16. Awinch l7 isjournaled in hearings in the standards 11, and to the same is attached a cord or rope 18, which passes around the outer side of the trolleysheave and is connected tothe section 3, as at 19. By this means the outer section 3 of the flexible pneumatic conveying-tube may be raised or lowered, as will be understood.

A verticalshaft 20is journaled in abearing 21, with which the arm 12 of the turning, ring 9 is provided. The said shaft 20 has at its upper end a hand-crank 22, by means of which it may be rotated, and has at its lower end a pinion 23, which engages the spur-ring 8. The lower section of the pneumatic feed-conveying tube being secured to the sleeve 5 and the latter being swiveled in the spurring, it follows that by means of the pinion 23 and said spur-ring, which latter is fast on the fan or blower casing, the tube may be swung in any desired direction.

The outer section 3 of the pneumatic tube is detachably secured on the upper outer sec tion 24 of the flexible elbow 4, which is of the construction here shown. Spring-catches 25 are attached to the section 3 and engage openings 26 therein and in the section 2i of the flexible elbow, said spring-catches serving to secure the said section 3 to the said section 24, as will be understood. Hence the section 3 is adapted to be detached from the flexible elbow at will.

At the outer endof the section 3 is a flexible elbow-cap 27, which is composed of the telescoping sections 28 29, pivotally connected together, as at 30. Said section 29 is attached to the outer end of section 3, as at 31. A rod 32 is connected to a lug 33 on the upper side of section 28 and operates in an opening in a lug 34: on the section 3. A coiled extensile spring 35 on said rod bears between said lugs 33 34 and, serves normally to depress the outer section 29 of said cap 37. A cord 36 is attached to said rod 22 and enables the said cap to be turned to any desired angle with relation to the outer end of section 3, and said cord may be secured to a lug or ear. 37 on the said section 3 at a point'where it is in convenient reach of the operator.

Having thus described our invention, we claim.-

.1. In apneumatic conveyer-tube of the class described, a lower section, a flexible elbowsection thereon, an outer section detachably secured to said flexible elbow-section, an elbow-cap at the outer end of said outer section,

said cap comprising a pair of telescopicallyfitted sections one pivoted to said outer section and said telescopically-fitting sections being pivotally connected together on one side, a rod connected to the outer cap-section, a guide on said outer section for said rod, a spring on the latter, bearing against said guide and said outer cap-section, to normally depress the latter, and an operating-cord attached to said rod, substantially as described.

2. The combination of a pneumatic conveying-tube having a lower section 2, the cylindrical sleeve 5 on the lower end of said lower section and in which the latter is secured, said sleeve having the base-ring 6, the spurring in which said sleeve is revoluble, said spur-ring bearing on said base-ring, means to secure said spur-ring on a support, the turning ring secured to said sleeve and bearing on said spur-ring, and a pinion carried by said turning ring and provided with means whereby it may be rotated, said pinion meshing with said spur-ring, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
